I have a very strange problem with QGC and don't know where to ask for a solution.Maybe you've heard this before or can give me a hint.

System: WIN 7/64 bit and AQM4, AG QGC 1.6.3.1

Everything was fine and somwhere during configuration of the M4 the QGC crashed.Now even after disconnecting the M4 and a reboot, the software always hangs during startup at the same point.The procedure on the splash screen says: "Restoring last view state".Also no luck with a fresh download in a separate folder.What can I do?

Usage: qgroundcontrol_aq.exe [options]Ground control station for AutoQuad flight controller and other MAVLink compatible robots.

Options: -?, -h, --help Displays this help. -v, --version Displays version information. --fresh Back up then delete all program settings and start fresh (also see -swap). NOTE that only ONE BACKUP VERSION IS KEPT! --swap Back up current settings, then restore and use previosly backed-up settings. If no backup exists, acts same as -fresh. --nobak When used with --fresh or --swap, do NOT back up current settings first (this preserves the previous backup, if any, but you will LOOSE ALL CURRENT SETTINGS!). --console Keep the command-line console open/attached after startup (useful for debug, etc). Redirect output to a file to create a log, like this: `qgroundcontrol_aq --console >>qgclog.txt`

The command line is good for testing the serial connection. In your case it tried to restore the previous view.I had a similar incident solved by changing CURRENT_VIEW in the ini file and that solved the crashes.
